Original Abstract Submitted
A phosphor includes a phosphor phase made of ABO:Ce having a garnet structure; and a matrix phase having a refractive index higher than a refractive index of the phosphor phase. A content of the phosphor phase is 56 vol % or more and 70 vol % or less in terms of a volume ratio with respect to a total including the matrix phase and the phosphor phase. A is at least one selected from the group consisting of Lu, Gd, Tb, Ga, and Y. B is Al.
